If anyone ever asks you what were the last Snake and Mongoose cars released by Hot Wheels in the Redline era, you might first ask them why they asked such a wordy question about such an obscure subject. Then you can tell them the answer- these:
These are the Rear Engine Snake and Mongoose from 1972. By this time, Mattel had pretty much run the gambit on the racing duo. Other cars would be released and re-released in the future, but these were the last of the original Redlines.
I found these on eBay a few years ago (not together). These aren't cheap, but if you wait long enough you can get some deals. These are fairly clean with very nice stickers, so I got pretty lucky.
Although they aren't the most popular Redlines from the series, I think they're pretty cool! I'll keep 'em!
So now you know!
Until next time keep searching for treasure!
